무릇 산 자는 죽을 줄을 알되 죽은 자는 아무 것도 모르며 다시는 상도 받지 못하는 것은 그 이름이 잊어버린 바 됨이라

And on this, our Sages of blessed memory commented (Berakhot 18a) that “the living know that they will die” (Ecclesiastes 9:5) refers to the righteous, etc., meaning that they know they will die and therefore the remembrance of the day of death is constantly before their eyes, and this saves them from sin. And the dead know nothing refers to the wicked, who even during their lives are called dead, as it is said, And you, O corpse, wicked one, etc., whose day has come, in the time of the iniquity of the end (Ezekiel 21:30). Meaning, the wicked know nothing because the remembrance of the day of death is not before their eyes at all. And this is what it means when it says, whose day has come, in the time of the iniquity of the end, meaning, because of the sin regarding his end, for the remembrance of his end was not before his eyes at all. Unlike David, who prayed and said, Lord, make me know my end, etc. (Psalms 39:5), but rather their inner thought is that their houses will last forever (Psalms 49:12). And this is a precious interpretation.
Ramban
IN THE DAY THOU EATEST THEREOF THOU SHALT SURELY DIE. At the time you eat of it, you will be condemned to die. Similarly, we find: On the day thou goest out, and walkest abroad any whither, thou shalt surely die.350I Kings 2:42. Said by Solomon to Shimi, that on the day he goes outside of the limits of Jerusalem he shall surely die. This does not mean that he [Shimi] is to die immediately on that day; nor does it refer to his mere knowledge thereof, namely that he is to know that he will die eventually for all the living know that they shall die.351Ecclesiastes 9:5. But it does mean that at the time he [Shimi] goes forth from Jerusalem, he is liable to death at the hand of the king, and he will slay him when he pleases. [Similarly, in the verses:] But they shall not go in to see the holy things as they are being covered, lest they die;352Numbers 4:20. And they shall not bear sin for it, and die thereby.353Leviticus 22:9. Their intent is [not that those who transgress against these prohibitions will die immediately], but only that they will be liable to death and will die on account of this sin of theirs.
Now in the opinion of men versed in the sciences of nature, man was destined to die from the beginning of his formation, on account of his being a composite [of the four elements, and everything that is composite must revert to its original components]. But now He decreed that if he will sin he will die on account of his sin, like those who are liable to death at the hands of Heaven for such sins as a non-priest eating the Heave-offering, or a priest who has drunk wine or who does not wear the [required number of priestly] garments when performing the Service in the Sanctuary, and other cases. There the intent is that they will die prematurely on account of their sin. This is why in stating the punishment [after Adam ate of the fruit of the tree of knowledge] He said, Till thou return to the ground; for out of it wast thou taken; for dust thou art, and unto dust shalt thou return,354Genesis 3:19. by your nature. In the beginning before he sinned, Adam also ate of the fruit of the tree and of the seeds of the earth; and if so, there was bound to be depletion in his body, and he was subject to the cause of existence and destruction. [Thus the opinion of the men of science.]
But in the opinion of our Rabbis,355Shabbath 58b. if Adam had not sinned he would have never died, since the higher soul bestows life forever, and the Will of G-d which is in him at the time of his formation would always cleave to him and he would exist forever, as I have explained in the verse, And G-d saw that it was good.356Above, 1:10.
Know that composition indicates destruction only in the opinion of those wanting in faith, who hold that creation came by necessity. But in the opinion of men of faith who say that the world was created by the simple Will of G-d, its existence will also continue forever as long as it is His desire. This is clear truth. That being so, In the day thou eatest thereof thou shalt surely die means that then you will be condemned to die since you will no longer exist forever by My Will. And the matter of eating [from the other trees] was to Adam at first only a source of enjoyment.357Ramban is aiming to answer the question: If Adam was destined at first to exist forever on account of his superior soul, what purpose did his eating serve? Ramban answers that, according to this theory, he ate not out of necessity but for enjoyment. And it is possible that the fruits of the garden of Eden were absorbed in his limbs as the Manna, and they sustain those that eat them. But when He decreed upon him, And thou shalt eat the herb of the field358Genesis 3:18. and with the sweat of his face he shall eat bread of the earth,359Ibid., Verse 19. this [the food] became a cause for decomposition since he is dust, and dust he eats, and unto dust he shall return.

Rabbeinu Bahya
ובארצכם לא תעשו, “and in your land you shall not do so.” Seeing the Torah had mentioned such defects as damage to the reproductive organs earlier in our verse, the Torah adds that it is forbidden to castrate animals in the land of Israel even if such animals were not intended as offerings. Even animals which are not fit for consumption by Jews must not be castrated. Contrary to the first impression that the word בארצכם, “in your land,” suggests that only in the land of Israel is it forbidden to castrate animals, this is misleading, and castrating G’d’s creatures is forbidden everywhere. The only reason the Torah wrote that word was to emphasize that even in our land where many of these animals cannot serve the general population as food seeing the animals in question are ritually impure, we must still not castrate such animals as a means of keeping down their numbers.
It is also possible that the use by the Torah of the word תעשו here points out that castrating an animal is equivalent to “undoing it;” G’d made it, we undo it but allow it to live at the same time preventing it from procreating. We find a similar use of the word לעשות in Kohelet 4,17 where Solomon speaks about כי אינם יודעים לעשות רע, “for they do not know that they are to destroy the evil and remove it.” At first glance we would have translated the verse as “they do not know how to do evil,” something that clearly does not fit the context of the verse.“ [Rashi does not have trouble with the ordinary meaning of the word לעשות in that verse. Ed.] Another verse in which the word עשה does not have the meaning which it usually has is Genesis 9,24 where the Torah speaks about אשר עשה לו בנו הקטן, normally translated as “which his younger son had done to him,” (Noach who had been naked in his tent). On the face of it, the son (Cham) had done nothing except tell his brothers that their father had uncovered himself while drunk. Nonetheless, our sages in Sanhedrin 70 use the word to mean that he had castrated his father. So we see that the word עשה, though normally meaning “did” in a constructive sense such as when G’d created the universe, may appear in exactly the opposite sense such as when depriving the animal of its regenerative potential by castrating it. This may also be the meaning of the word יעשנה in Proverbs 6,32, where Solomon writes משחית נפשו יעשנה, which at first glance looks as if he says that “he who destroys his life is really creating it.” Instead, the meaning is “if he wants to destroy himself let him do such a thing (commit adultery).” When someone destroys his soul, his life, he most certainly deprives (יעשנה) it of the opportunity to achieve its lofty aims..”
